The "advantage" part depends on the needs of each system. Some benefits of ECC are that it helps overcome problems with occasional false flash reads, and buffered writing can be faster. Direct write through with NOR dramatically reduces the chances of corruption due to an interrupted write. Linux does determine if you have NOR-ECC and enables buffering. Buffering is a must because you can call the file write function numerous times, even to write one byte at a time. NOR-ECC only allows one write per page before an erase so the writes are buffered before they are committed.
